Title

DESIGN OF G+15 MULTISTOREY BUILDING STIFFENED WITH BRACING

Abstract

This Paper work focuses on comparison of seismic analysis of G+15 building stiffened with bracings. The performance of the building is analyzed in Zone II, Zone III, Zone IV, Zone V. The study includes understanding the main consideration factor that leads the structure to perform poorly during earthquake in order to achieve their appropriate behavior under future earthquakes. Earthquake is the natural calamity, it produce strong ground motions which affect the structure. Small or weak motions that can or cannot be felt by the humans. Provision of shear walls and bracings are installed to enhance the lateral stiffness, ductility, minimum lateral displacements and safety of the structure. Storey drift and lateral displacements are the critical issues in seismic design of buildings. Due to Industrial revolution, availability of jobs and facilities, population from rural area is migrating towards cities. Because of this metro cities are very thickly populated. Availability of land goes on decreasing and land cost also increases. To overcome this problem the use of multistoried buildings is must. But such provisions increases self weight and live load along with earthquake forces. With increase in height stress, strain, deformation and displacement in the structure increase which ultimately increases the cost of construction due to increased cross-sections of the elements. Multi-storey buildings are designed to carry gravity loads as well as earthquake loads and their combinations. I.S. codes providing these loading combinations for which structure need to be analyze and design. The analysis is aimed at finding the internal forces in component of structures and to find displacements developed in the structure leading to the development of strains. Structure must be safe from both strength viewpoint and serviceability as well. While vertical forces are most significant, the primary problem for most structures is force in the horizontal or lateral direction, which tends to subject buildings to large horizontal distortion. Therefore, most buildings are designed with lateral-force-resisting systems to resist the effects of earthquake forces. Bare frames are found to be more flexible and have large section requirement to with stand forces induced. The same can be minimizing by making structure more rigid. In this volume, use of bracing to increase the stiffness of structure has been resorted to on the basis of previous work done on.The crosstype, diagonal- type concrete bracing separately. The cross- type, diagonal- type of bracing system has been used. A number of structures with same height and width with and without braces have been analyzed. The responses of braced frames of different configurations have been compared with each other and the same also have been compared with unbraced frame. For all type of structures which are serving more economy for particular type, it was found that the lateral displacements are well within the acceptable limit as per IS 1893:2002.
